ANTIFREEZ ING DRINKING-FOUNTAIN FOR POULTRY.

Specification of Letters Patent.

Application filed February 1, 1910. Serial No. 541,348.

To all whom it may concern:

Be it known that I, WILLIAM H. Asrr- CRAFT, a citizen of the UnitedStates, residing at Janesville, in the county of Rock and State ofWVisconsin, have invented certain new and useful Improvements inAntifreezing Drinking- Fountains for Poultry, of which the following isa specification.

My invention relates to drinking fountains for poultry and has for itsobject the provision of a device that is adapted for use in freezingweather and consisting of a casing containing a lamp, and a trough andsupply tank seated in the casing, the heat generated by the lamp servingto prevent the contents of the tank and trough from freezing.

The construction and operation of my improved drinking fountain will bedescribed in detail hereinafter and illustrated in the accompanyingdrawings in which- Figure l is a side view in elevation of my improveddrinking fountain, and Fig. 2, is a central vertical sectional view.

In the drawings similar reference characters indicate correspondingparts in the several views.

The base casing 1 of my improved fountain has its sides perforated asshown at 2 to admit air to the lamp 3 but which are small enough toprevent combustible litter, that may be kicked up by the fowls, fromentering the casing and coming in contact with the flame of the lamp.

4: indicates a flange extending inwardly from the side of casing 1adjacent to its top edge on which is seated the drinking trough, whichconsists of a dish-like receptacle having a central opening 6 thereinslightly larger in diameter than the flue 7 of the lamp 3, and 8indicates an upstanding flange surrounding said central opening, saidflange being preferably made higher than the rim of receptacle 5, thoughit is not essential. The flange 8 being spaced apart from the flue 7provides an air space 8 that permits circulation of air between the flueand flange to prevent the water in the trough from getting over-heatedand the parts from melting when the tank is empty.

The supply tank consists of an inverted open-ended cylinder 9 secured tothe receptacle 5 by means of hooks 10 or an equivalent releasablefastening, 9 indicating the water feed.

11 indicates a heating dome secured centrally of the open end of thetank cylinder by means of cross pieces 12, said dome consistingessentially of an inverted cup-shaped receptacle having its edge on thesame plane as the edge of the tank.

13 indicates a tubular outlet duct for the products of combustion fromthe lamp 3, connecting the top of the dome 11 and the outer portion ofthe tank 9, said inclined construction of the duct being designed tomost effectually catch the heat-rays from the products of combustionpassing through the duct.

14; indicates a handle pivotally secured to the top of tank 9 forconvenience in handling the tank and trough.

In operation the tank 9 is filled when in an inverted position, thetrough is then placed in position on the tank and secured thereto bymeans of hooks 10. When the tank and trough are turned over the waterwill pour through hole 9 until the trough is filled up to the top of thehole when the pressure of the atmosphere on the water in the trough willovercome the pressure of the air and water in the tank and the waterwill not rise any higher in the trough. As the water is used out of thetrough so that the hole 9 is partly exposed air will enter the tank andsufficient water will pour out to again fill the trough up to the top ofthe hole 9*, this action of the tank and trough continuing until thewater in the tank is on the same level as the water in the trough.

By placing the trough and tank in the base casing 1 where the trough isseated on flange 4: the fountain is best adapted for full grown fowls aselevating the trough prevents them from filling it with trash and dirtin scratching, and in cold, freezing weather the water in the tank andtrough may be kept from freezing by burning the lamp 3, the heattherefrom not only warming the water in the tank but also taking thechill off of the water in the trough, the construction by which thetrough seats inside of the casing 1 admitting of the base of the troughand its outer edge being heated by the lamp so that ice cannot formtherein.

Having thus described my invention what I claim is 1. In a poultrydrinking fountain, a casing, a lamp contained in said casing, a drinkingtrough seated in said casing and having an opening to receive the lampflue, an upstanding flange surrounding said opening, said flange beingspaced apart from the lamp flue, a sup ly tank consisting of an invertedopen-en ed c linder seated in said trough and having a eed hole in itsside, a heating dome secured in said tank and inclosing the flangedopening in the trough, and an outlet duct leading from said dome to theoutside of the tank.

2. A poultry drinking fountain comprising a casing having perforatedsides, an inardly extending flange adjacent to the top of the casing, alamp contained in the casing, a drinking trough seated on said flangeand having a central opening therein to receive the lamp flue, anupstanding flange surrounding said opening and spaced apart from thelamp flue, a supply tank consisting of an inverted open-ended cylinderremovably secured in the trough and having a feed hole in its side, aheating dome secured in said tank and inclosing the flanged opening inthe trough, and an outlet duct leading from said dome to the outside ofthe tank.

In testimony whereof I hereto affix my signature in the presence of twoWitnesses.
